Slayer
A super fast dual-blade assassin. Slayer is deadly in 1v1 and small fights with crit bursts and mobility.
Strong vs:
Gun Crusher, Light Wizard
Weak vs:

Slayer is built for speed and pressure. You jump in, burst hard, then reposition before the enemy can react. Slayer is popular for duels because the damage comes fast and the movement is tricky to read. In group fights, you pick off weak targets and escape. In matchup charts, Slayer can do well into Gun Crusher and Light Wizard, but Grow Lancer and Rune Wizard are dangerous enemies for you.
